Abstract

We sought to investigate the prescence of "isolated" diastolic disease, defined as reduced long-axis early diastolic velocity with normal systolic velocity, in 21 young patients with left outflow tract obstruction. Most patients had depressed systolic velocities despite normal ejection fractions. The close relations amond long-axis velocities suggest isolated diastolic disease is unlikely.

摘要

我们试图在21例左心室流出道梗阻的年轻患者中，研究“孤立性”舒张期疾病的存在情况，该疾病定义为舒张早期长轴速度降低而收缩期速度正常。尽管射血分数正常，但大多数患者的收缩期速度降低。长轴速度之间的密切关系表明孤立性舒张期疾病不太可能存在。
